The invention discloses a winch transmission unit capable of preventing a suspended steel truss platform from falling and being jammed. The winch transmission unit comprises a suspended steel truss and a plurality of winches, wherein the plurality of winches are evenly distributed on a construction platform at the upper end of a silo in the circumferential direction; the suspended steel truss is hoisted at the inner side of the silo through the winches and slides downwards; The winch transmission unit further comprises a driving motor, first chain wheels, a second chain wheel, a chain and bevel gears, wherein the plurality of winches are synchronously driven by one driving motor; an output shaft of the driving motor is longitudinally arranged; the first chain wheels are arranged on the output shaft of the driving motor; the first chain wheels are in transmission connection with the second chain wheel through the chain; the second chain wheel is coaxially provided with the bevel gears;a winch spindle is coaxially provided with the bevel gears; and the two bevel gears are in engaged transmission. The winch transmission unit has the beneficial effects that the 3 to 4 winches are synchronously driven by one driving motor, so that the suspended steel truss platform descends in a horizontal state, and the suspended steel truss platform can be prevented from being jammed by scrapingand touching the inner wall of the silo in the descending process.
